What is FRCM?

Repair, protect and strengthen aging, damaged or overloaded concrete and masonry structures in one application and significantly reduce your installed cost.

FRCM or Fabric-Reinforced Cementitious Matrix combines high-performance sprayable mortar with a carbon-fiber grid to create thin-walled, reinforced concrete shells without adding significant weight or mass to the structure.

Benefits

  • Repair and strengthen structures using only a thin layer of material
  • Can be applied in multiple grid layers (four maximum) to achieve desired strengthening – ½”-1” (12.7-25.4 mm) thick for one-layer grid applications, adding ½” (12.7 mm) for each additional grid layer
  • Lightweight system for vertical surfaces and overhead applications
  • Suitable for harsh environments or service conditions including marine locations, elevated temperatures, humidity, abrasion and UV
  • Works on damp substrates
  • Installation process is similar to that for wet shotcrete repair mortars
  • Quick installation with less preparation than traditional shotcrete repairs with rebar
  • Does not create a vapor barrier
  • Matches substrate finish
  • 100% solids formulation
  • Carbon-fiber grid features excellent chemical and corrosion resistance
  • Non-hazardous shipping
FRCM application
The cementitious matrix repairs surface defects and bonds the system to the substrate in one step.

FRCM System Products

The FRCM system consists of two components: a sprayable, polypropylene-fiber-reinforced cementitious matrix and a carbon-fiber grid.
